Specification of Letters Patent No. 3,339, dated November 15, 1843.

To all whom it may concern Be it known that I, B. F. GREENOUGH, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented a new and useful Improvement in burning the combined vapor ofchemical oil or other mixture of which spirits of turpentine is thebasis with the vapor ofwater; and I do hereby declare that the followingis a full, clear,

and exact description thereof, reference being had to the accompanyingdrawing, showing a section of the apparatus.

The nature of my invention consists in passing a current of steam fromboiling water through chemical oil, spirits of turpentine, or otheranalogous substance and conveying the united steam or vapor throughproper pipes to be burned, the vapor issuing from the burner by means ofthe pressure of the steam.

Theconstruction of my apparatus is as follows: A suitable boiler A, ofany construction having a fire under it is furnished with a pipe B, thatleads from it to the reservoir C, containing the material to be burnedthe pipe running nearly to the bottom. The reservoir C, must be steamtight, as well as theconnection of the pipe B, with it. This reservoirisfilled with the material to be burned in sufiicient quantity to supplythe burners, and from or near the top of the reservoir one or more pipesD lead to the burners placed in any convenient position for givinglight, or the burner may be attached directly to the reservoir; but Iprefer the first named arrangement as being more convenient. The pipes Dshould have an inclination from the burner down toward the reservoir sothat any condensed vapor may run back into said reservoir; but if it isfound necessary to incline the pipe the other way a small cistern orreceiver E can be C nnec ed with it at the lowest point generates itthrough the and from which it may be drawn.

The burners G, may be formed like Argand orother shaped gas burners andtheir fittings may be similar.

When the apparatus isput in operation the steam generated in the boilerpasses through the pipe into the reservoir with 'Wl11Cl1 1t is connectedandwhen the material for burning is sufficiently heated the steam andvapor therefrom arising ascends in about equal proportions through thepipes to the burners; in the commencement of this process the vapor willbe condensed and run back till the pipes are sufficiently hot when itwill issue from the burners and can be lighted and will burn similar togas from coal, the vapor or gas being driven forward by the pressure ofthe steam that pipes to supply the burners, which supply may beregulated by stop-cocks as in gas-fixtures. One or more burners may beattached to a pipe and conveyed to the most convenient place for burningaway from the reservoir and consequently from any danger of exploding;the fire which generates the vapor is also far enough removed from thereservoir to prevent any accident.

What I claim as my invention and desire.

to secure by Letters Patent is- Combining a reservoir having burnersattached thereto by pipes or otherwise, with a steam boilersubstantially in the manner described, so that the vapor generated bythe steam will be forced throughthe turpentine pipes to the burnersunder the pressure of the steam for the purpose set forth.
